Of all the various uses for Cannabis plants, add another, “green” one to the mix.

Researchers at UConn have found that the fiber crop Cannabis sativa, known as industrial hemp, has properties that make it viable and even attractive as a raw material, or feedstock, for producing biodiesel – sustainable diesel fuel made from renewable plant sources.
The plant’s ability to grow in infertile soils also reduces the need to grow it on primary croplands, which can then be reserved for growing food, says Richard Parnas, a professor of chemical, materials, and biomolecular engineering who led the study.
“For sustainable fuels, often it comes down to a question of food versus fuel,” says Parnas, noting that major current biodiesel plants include food crops such as soybeans, olives, peanuts, and rapeseed. “It’s equally important to make fuel from plants that are not food, but also won’t need the high-quality land.”
Industrial hemp is grown across the world, in many parts of Europe and Asia. Fiber from the plant’s stalk is strong, and until the development of synthetic fibers in the 1950s, it was a premier product used worldwide in making rope and clothing.
